postfix problem, can't send email

[blueblue]

Hi!
I have installed a server mail with postfix on Ubuntu 6.06. I can send email to local email adress, but I can't send email to external email.

This is the message in /var/log/mail.log
postfix/qmgr[8024]: warning: connect to transport smtp: Connection refused

This is the querys that postfix does, from /var/log/mysql.log

mail@localhost on maildb
SELECT destination FROM aliases WHERE mail='domainofemail' and enabled = 1
mail@localhost on maildb
SELECT domain FROM domains WHERE domain='domainofemail' and enabled = 1

I use mysql to store users, aliases and domains.

This is my configuration files:

Thanks a lot!

Please show "postconf -n output", and your entire master.cf.

[Mr. C.]

Assuming your log entry was the same as the OP's:

postfix/qmgr[8024]: warning: connect to transport smtp: Connection refused

Had you recently changed this line in master.cf?

smtp unix - - - - - smtp

What is shown here is correct, but the symptoms indicate it was different than this previously (the private entry would have been an 'n').

If so, restart postfix.

[DDuong]

There is one entry that "might" need to be changed to test things out.

In my main.cf file, I have this for the follow field:

mydestination = localhost.$mydomain, localhost

After trying this, please restart postfix and try again.
